Yesterday I rejoined one of the most athletic guys I know, and he taught me both the most insane and brilliant exercises I've ever tried in a gym. His name is Anthony Field, and yes ... he's the Blue Wiggle from the children's TV show The Wiggles.

Anthony and I have trained together before, and he's impressed me each time. But yesterday ... I have a hard time finding words to describe. He started doing pull-ups almost two years ago, and he lost about 40 pounds. Then he added rings to his routine, which made things more fun. And now, well, the average person would just think he's lost his mind.

He is addicted to strength training while using nothing but his body weight, and his physique is proof that this strategy works like a charm. We spent a ton of time in a hotel gym shooting a bunch of fun and exciting fitness segments, which I'll be airing here soon. We giggled through it, but mostly because he doesn't speak "American" and I'm not so good at "Australian."

Anyway, I can't wait to show you the dozens of training techniques I'm positive you've never seen before on video -- but for now, this photo gallery will have to do.
